GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 593,342, dated November 9, 1897.

Application filed April 20, 1897. Serial No. 633,058. (No model.) I

To 60% whom it may concern:

- Be it known that we, AUGUST E. VoeLER, a subject 'of the Emperor of Germany, and a resident of Hoboken, Hudson county, State of New Jersey, and CHARLES G. RICHARDSON, a subject of the Queen of Great Britain and Ire land, and a resident of New Brighton, Richmond county, State of New York, have'invented certain new and useful Improvements in Gas-Burners, of which the following is'a specification.

Our invention relates to improvements in gas-burners, especially such as are adapted for use with incandescing mantles.

The purpose of the invention is to provide simple and efficient means for producing thorough admixture of air and gas in the proper proportions for perfect combustion, so as to prevent the deposit of unconsumed carbon upon the mantle and secure the best heating and illuminating effects from the flame.

Referring to the drawings which accompany the specification to aid the description, Figure 1 is a vertical section of our burner and showing a chimney and mantle in position. Fig. 2 is an elevation of the same. Fig. 3 is a cross-section on the line 3 3 of Fig. 1. 1 Fig. 4 is a detail showing the preferred mode of retaining the rod which supports'the mantle in position.

A is a shell or case of sheet metal and preferably of globular form, as shown, to give a large area for the gas and air to mix in around the tip B, which is threaded into the threaded inturned sleeve a of said shell A. Said tip B is also internally threaded for a gas connection and is provided with the usual perforated diaphragm I). Said shall A is provided with an open-top sheet-metal sleeve C, secured to the said shell by being pressed partly around the head I), as shown, or said sleeve 0 may be formed integral with said shell A, and cl is a slot in said sleeve for the passage of the transverse shaft E, provided with long pinion-teeth efor operating the tube F, which regulates the air-supply, as will be hereinafter described. The sleeve g of the chimney-gallery G fits on said sleeve 0 and is perforated at h to admit air to the said shell A, H being the usual ring for supporting a globe if one is used. The combined mixingchamber and burner-head J, of sheet metal, fits in said sleeve g, being shouldered, as at j, to properly position it in said sleeve. A short distance below the top of sleeve g said burner-head turns rather abruptly inward, as at 7c,and thence descends as a neck or sleeve I nearly to the bottom of the aforesaid sleeve 0. Said neck Z constitutes a guide-sheath for the aforesaid regulating-tube'F, which is pro vided in one side with rack-teeth m, which mesh with the pinion-teeth e of shaft E. Said tube F may either bear-ranged inside sleeve Z, as shown, or outside said sleeve, it only being necessary that it should be'capable of motion toward and from the tip B; Said shaft E is positioned by a transverse sleeve n, carried by the sleeve g of the chimney-gallery.

To facilitate assembling the parts, said shaft E, with its teeth e, and also the sleeve n are made slightly tapering, as shown, and said shaft E may be provided with a suitable pin or shoulder e to prevent longitudinal displacement, if desired. The rack-teeth on the regulating-tube F do not extend quite to the ends of said tube, so that the play of the tube is limited, and the turning of the shaft E cannot entirely displace'said tube.

A finely-perforated diaphragm p, such as wire mesh, is placed in the burner-head J just above where it narrows, as shown. Said diaphragm 19 increases the efiective mixing of the air and gas and also prevents the flame from working back to the gas-supply pipe. A ring 0, of some non-conducting material, as soapstone, provided with reduced upper and lower edges which fit snugly into the upper end of said burner-head J and into the lower end of the cap R, insulates said cap from and keeps the lower parts of the device cool. Said cap R constitutes the top of the burner proper and is'perforated with radial slits'r, through which the mixed gas and air escape to the flame. Said cap R may be provided, if desired, with a dependent socket s for the lower end of the rod which supports a mantle S, but we prefer to carry the mantle-supporting rod T down outside the mantle and fasten its end in a hole in a block 20, carried on the chimneygallery G, by a set-screw o,Wbeing any usual chimney.

In use the operator turns the shaft E by a key E, which fits the square end of said shaft,

chamber can be used than is now required, a

and a shorter chimney suffices to produce the requisite incandescenceof the mantle. The eflicient operation of the device is also promoted by the fact that the air becomes considerably heated as it descends the chimney and the sleeve 0 on its Way to'the point where it mixes with'the gas, thus producing a regenerative eifect.

Referring to Figs 4*, the rod T is clamped in position by the spring X, which is formed of a single piece of elastic metal and with two leaves w m, as shown. Said spring is soldered to thesleeve got the chimney-gallery. There is ahole in the upper leaf in line with a hole ,2, which is formed in a suitable projecting part of the gallery. A slot y in the lower leaf so of said spring X is normally out of line with said holes ya, so as to clamp and hold the rod when in place in said holes. To release the rod, the user presses the lower leaf upward to the position of the dotted lines, thereby bringing slot y into line with holesy z and freeing said rod.

Now, having described our improvements, we claim as our invention 1. The combination with the shell A burnertip B and burner-head J, of the verticallyadjustable tube F movable in said shell A and adapted to seat onsaid tip B and constitute a valve for regulating the air-supply, 1

pipe, air-inlets communicating with the up per part of said shell, a regulating-tube movable in said shell and adapted to seat on said burner-tip and constitute an air-regulating valve insaid shell, a pinion for reciprocating said tube, a combined burner-headand and outlets for mixed gas and air in said burner-head, substantially as described.

3. The combination of a shell provided with a burner-tip connecting with a gas-supply ,pipe, air-inlets communicatingwith the upper part of said shell, a regulating tube' movable in said shell and adapted to seat on said burner-tipand constitute an air-regulatin fvalve in said shell, a pinion for re'cipioca't in g said regulating-tube, a combined burnerhead and mixingchamber communicating with said regulating-tube, outlets for mixed air and gas in said burner-head,-a mantlesupporting rod, a socket,and' a set screwifor L magma mixing-chamber communicating with said regulating-tube, a" diaphragm in said head,

said rod outside the burner-head, subst'an tially as described.

4. The combination of a shell A provided with a burner-tip B connecting with ag'as=' supply pipe and with inlets for air, aregulat ing-tube movable in said shell A and adapted to seat on said burner-tip B and constitute an air-regulating valve, a pinion for reci;pro-' eating said tube, a combined mixing-chamber and burner-head communicating with 'said tube, an insulating-ring in the wall of 1 said burner-head, and acap on said ring pro l vided with outlets for mixed gas and air, sub

stantially as described;

In testimony that we claim the foregoing'as our invention we have signed our namesgin presence of two'witnesses, this 31st'day of March, 1897.
